APPARATUS FOR TREATING FABRICS WITH FLUIDS- SPECIFICATION forming part of Letters Patent No. 779,076, dated January 3, 1905.

Application filed October 26, 1903. Serial No. 178,530.

To ctZZ whom, it may concern:

Be it known that I, JULIUS GEBAUER, a subject of the King of Prussia, Emperor of Germany, whose postofiice address is No. 87 Berlinerstrasse, Charlottenburg, near Berlin, Prussia, German Empire, have invented new and useful Apparatus for Treatment of Fabrics and the Like with Fluids, of which the following is a specification.

It has been frequently attempted to subject fabrics and other materials in an extended or opened-out state and in a continuous manner to the action of fluids or chemical solutions; but the apparatus and devices hitherto constructed or proposed for this purpose have the disadvantage that their output is very small, principally because the goods are while moving continuously exposed for too short a If, on the other hand, the goods be treated in rolls, they oppose great resistance to the uniform and complete penetration of the fluid or solution and act somewhat like filters, so that the outer layers are more acted upon by the fluid or solution than are the inner layers. Thus the main condition required, for example, for removing scales, burls, adherent particles of wood, and the like-namely, a good circulation of the fluid or solution at the highest possible temperatureis not fulfilled, and the reduced output of such apparatus is the principal reason why the treatment of goods in an extended state has not superseded the treatment in an nnextended state. These disadvantages are obviated by the apparatus which forms the subject of the present invention.

In the accompanying drawings, Figure 1 shows in longitudinal section, and Fig. 2 in cross-section, an apparatus constructed in accordance with this invention. Fig. 3 shows a part of one of the conveyers.

The apparatus comprises a series of conveyers a, arranged one above the other, on which the goods laid in folds of any suitable length are supported and caused to traverse a closed chamber Z), wherein they remain for.

any desired time in contact with the fluid or solution, which for the purpose of description I will refer to as lye. The said chamber is provided at each end with spaces 0 0, into which dip division-plates (Z, so as to constitute liquid seals to close the said chamber against the entrance of air, and therefore a pressure higher than that of the atmosphere can be maintained in the said chamber. In the said chamber Z) and in the spaces 0 c are arranged several guiding-rolls e e e c e 0 a folding device f, and the several endless conveyers a for supporting the goods. Over these conveyers a are arranged injecting-pipes g, which properly distribute the lye, and between the conveyers are arranged radiators or steampipes 71, which increase the temperature of the lye by radiation. The lye is preheated in the preheater t', connected by piping with the injecting-pipes Below the apparatus is a collecting vessel Z, into which the superfluous lye runs and from which it is returned to the heater c' by a rotary or other pump m. Beneath the three upper rows of conveyers a are arranged lye-collectors a, which catch the lye passing through the goods on these conveyers and either returns it (if still further utilizable) to the collecting vesselZ or allows it to run out of the apparatus. The rear end of the apparatus is provided with rolls 0, by which the goods are drawn from the apparatus and squeezed. The conveyers are carried over shafts t, operated by vertical shafts and driven by worms and worm-wheels that are actuated by bevel-wheels r and pulleys s, so that they travel in opposite directions, and they project alternately at one end beyond the end of the one above. The conveyers themselves consist of metal strips 10 w, provided with holes w, in which engage the teeth of the driving sprocket-wheels, the said strips being connected by woven wirework y, constituting the conveyer proper, as shown in Fig. 3.

The operation of the apparatus is as follows: The goods are impregnated with lye in, for example, a three-roller machine 2, mounted in front of the apparatus, and are then passed over the guide-rolls e e 0 into the first liquid seal 0, which is filled with lye. They then pass over the roll of the folding device f, which lays the goods on the top conveyer a in uniform folds, so as to present a large surface to the action of the lye issuing from the injecting-pipes g and to the heat radiating from the steam-pipes it. The goods thus deposited on the first conveyer fall as they reach the end thereof onto the projecting end of the second conveyer arranged beneath the first and moving in an opposite direction. The goods on this second conveyor are again acted upon by lye and subjected to heat radiated from the heating-pipes. The goods pass thus automatically from one conveyer to the next one below, and when the goods reach the end of the lowermost conveyer they are conducted by a pair of rolls 6 onto guiding-rolls e e and thence through the rear liquid seal 0 to rolls 0, by which they are drawn forward and squeezed. Below the three uppermost conveyers a are provided lye-collectors n, which catch the superfluous lye passed through the goods and either discharge it into the collecting vessel Z or conduct it away from the apparatus. The lye passing through the goods on the other conveyers collects in the apparatus and passes therefrom to the collecting vessel Z, from which the said lye is by means of a rotary or other pump or pumped into the heater 2', which may be of any known or suitable construction, and be heated by steam. From the heater z'the lye is conducted through piping 70, arranged, say, outside the apparams, to the injecting-pipes g, from which it passes in a hot state onto the goods on the conveyers. The length of the path which the goods travel through the apparatus can be increased either by increasing the number of the conveyers or by lengthening them.

From the foregoing description it will be seen that this apparatus fulfils completely the conditions required for the thorough treatment of goods with fluids, ozonizing agents, chemical solutions, and the like for any required purpose. The goods are in shallow layers on the conveyers and are open to the action of the fluid or solution, which is heated very uniformly and to a very high temperature by the heat radiating from the steampipes h, and it is possible to work the apparatus at a pressure higher than that of the atmosphere. The apparatus thus gives uniform impregnation, the fluid or solution is maintained at a high temperature, and any desired length of exposure to the action of the fluid or solution can be obtained.
